HoRsEsHo-sHARPENme DEVICE.

Specification of Letters Patent.

Patented May 29, 1906.

Application filed September 6, 1905- Serial No. 277,142.

T0 at whom it may concern:

Be it known that I, JOSEPH BOMGARDNER, a citizen of the United States, and a resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented certain new and useful Improvements in Horseshoe-Sharpening Devices, of which the following is a specification.

My invention relates to improvements in devices for sharpening the calks of horseshoes while same may remain on the hoof of the horse.

The object of my improvement is to render such devices extremely simple, efficient, and practical in point of operation. I attain this object in a device constructed and arranged substantially as shown in the accompanying drawings, in which Figure 1 represents a plan view of said de vice. Fig. 2 is a central longitudinal section of same. Fig. 3 is an end view. Fig. 4 represents a transverse sectional view on line X X. (SeeFig.1.) Figs5and6showfraotional views of shoes with trimmed calks.

Like letters of reference denote like parts in the drawings and specification.

In the main my invention consists in a shearing device whereby calks while on the horses shoes can be trimmed from a flat shape into edge shape or from a dull condi tion into a sharpened condition. The application of such devices saves the trouble and expense of removing horseshoes should the calks thereof be simply in need of sharpening or trimming.

In the drawings, A represents a base or frame for and of the device.

Centrally and in longitudinal direction is movably embedded therein the cutter-bar B. At or near .one terminal of the frame is securely arranged a resisting member or plate C, and at or near the opposite end of the' frame is applied the fulcrumed lever D, by

which the bar is operated, as hereinafter described.

As shown, a dovetailed connection is formed for the plate upon the frame. However, other connections may answer equally as well. In central transverse direction said plate is formed to receive the shearing terminal a of the cutter-bar, the central depending part I) being of V shape and the portion a of the bar forming a counterpart therefor, which is forced against and past the face of said part b in the trimming operation of the calks. Eventually, however, the bar may simply serve as a plunger, and the calk may be forced along a stationary die or V-shaped member which opposes said plunger. In the latter instance the calk is moved by the plunger into the die, while in the former instance the calk remains stationary and the cutting or trimming end of the bar forces its way along the calk.

The short arm 0 of the lever D engages the jaws d of the bar, and upon swinging said lever the bar can be moved to and from the die.

The hoof of the horse is so placed upon the frame A that the calk of the shoe, appears in the depression e directly in front of the plate, there being the necessary clearance between said plate and cutter-bar when the latter is withdrawn, as shown in the drawings.

Having placed the calk in position, then the lever is drawn downwardly, and gradually the terminal (1 outs its way along the calk and trims the same from a flat shape into V shape. In other words, it sharpens the calk in a single operation simply by drawing the lever downwardly. Upon the return movement of the lever the hoof is removed, and the device is ready for the trimming of another calk.

Obviously compound levers or a rack and pinion or equivalent means may be employed in place of a single lever without departing from the nature of my invention. Figs. 5 and 6 show fractional views of trimmed shoes in side views, wherein the dotted lines indicate the dull condition or flat shape of calks.

If the calk is rather high, then a single V may be formed therefrom. (See Fig. 5.) If worn or low, two Vs are preferably formed, as shown in Fig. 6.

What I claim, and desire to secure by Let ters Patent, is

1. A device for trimming the calks of horseshoes comprising a base, a bar, being slidingly embedded therein, said bar having a V-shaped cutting portion projecting from near its front part and jaws at or near its rear part, a fulcrumed lever engaging said jaws and a resisting member for the calk undergoing trimming.

2. In a device for trimming horseshoecalks from a flat shape into V shape or approximately so, the combination of a suitable base, a bar slidingly arranged therein, said V-shaped depression all cooperating subsaid bar having in the front end thereof a V- stantially in the manner as and for the purshaped depression and the rear end adapted pose set forth. for engagement of a fulcrumed member JOSEPH BOMGARDN ER.
